Abstract:

LINE-1 (L1) retrotransposons constitute the dominant category of transposons in mammalian genomes. L1 elements are active in the vast majority of mammals, and only a few cases of L1 extinction have been documented. The only possible case of extinction in primates was suggested for South American spider monkeys. However, these previous studies were based on a single species. We revisited this question with a larger phylogenetic sample, covering all 4 genera of Atelidae and 3 species of spider monkeys. We used an enrichment method to clone recently inserted L1 elements and performed an evolutionary analysis of the sequences. We were able to identify young L1 elements in all taxa, suggesting that L1 is probably still active in all Atelidae examined. However, we also detected considerable variations in the proportion of recent elements indicating that the rate of L1 amplification varies among Atelidae by a 3-fold factor. The extent of L1 amplification in Atelidae remains overall lower than in other New World monkeys. Multiple factors can affect the amplification of L1, such as the demography of the host and the control of transposition. These factors are discussed in the context of host life history.

Abstract:

Abstract Oxytocin is a mammalian neuropeptide hormone that mediates behaviours important to reproduction. Despite almost universal amino acid sequence conservation across most groups of mammals, several unique forms have been reported across Neotropical primates. To explore sequence diversity, we investigated the genes encoding oxytocin and its receptor across the Atelidae, which was known to contain at least three unique oxytocin sequences. Additionally, we included the genus Cebus, within the Cebidae, to further explore the ubiquity of the Pro8 variant in this family. We found a novel amino acid variant (Val3) within the Atelidae radiation, bringing the total number of oxytocin sequences within Neotropical primates to seven. Analyses of physicochemical properties revealed conservative substitutions that are likely tolerated within the selective constraints imposed by receptor binding. Furthermore, we report radical substitutions at the eighth codon and evidence for co-evolution between Pro8 and a ligand-binding region of the oxytocin receptor in the Atelidae, supporting the notion that this variant may affect binding specificity. Overall, we suggest that selective constraint on binding specificity may maintain proper oxytocin function and that the diversification of amino acid sequence is likely due to a variety of processes such as relaxed constraint, neutral mutation, positive selection and coevolution.

Abstract:

Abstract New World monkeys (NWMs) occupy a critical phylogenetic position in elucidating the evolutionary process of major histocompatibility complex (MHC) class I genes in primates. From three subfamilies of Aotinae, Cebinae, and Atelinae, the 5′-flanking regions of 18 class I genes are obtained and phylogenetically examined in terms of Alu/LINE insertion elements as well as the nucleotide substitutions. Two pairs of genes from Aotinae and Atelinae are clearly orthologous to human leukocyte antigen (HLA) -E and -F genes. Of the remaining 14 genes, 8 belong to the distinct group B, together with HLA-B and -C, to the exclusion of all other HLA class I genes. These NWM genes are classified into four groups, designated as NWM-B1, -B2, -B3, and -B4. Of these, NWM-B2 is orthologous to HLA-B/C. Also, orthologous relationships of NWM-B1, -B2, and -B3 exist among different families of Cebidae and Atelidae, which is in sharp contrast to the genus-specific gene organization within the subfamily Callitrichinae. The other six genes belong to the distinct group G. However, a clade of these NWM genes is almost equally related to HLA-A, -J, -G, and -K, and there is no evidence for their orthologous relationships to HLA-G. It is argued that class I genes in simian primates duplicated extensively in their common ancestral lineage and that subsequent evolution in descendant species has been facilitated mainly by independent loss of genes.

Abstract:

The morphological and morphometric characterization of spermatozoa has been used as a taxonomic and phylogenetic tool for different species of mammals. We evaluated and compared the sperm morphometry of five neotropical primate species: Alouatta caraya, Ateles belzebuth and Ateles chamek of family Atelidae; and Cebus cay (=Sapajus cay) and Cebus nigritus (=Sapajus nigritus) of family Cebidae. After the collection of semen samples, the following parameters were measured on 100 spermatozoa from each specimen: Head Length, Head Width, Acrosome Length, Midpiece Length, Midpiece Width and Tail Length. Considering the available literature on sperm morphometry, we gathered data of 75 individuals, from 20 species, 8 genera and 2 families. These data were superimposed on a phylogeny to infer the possible direction of evolutionary changes. Narrower and shorter spermatozoa seem to be the ancestral form for Cebidae, with a trend toward wider and larger heads in derived groups. The spermatozoa of Atelidae may show an increase in total length and midpiece length. Sperm heads would have become narrower in the more derived groups of Ateles. Sperm length may increase in the more derived species in both families. Our results are discussed in the context of sperm competition and sexual selection.

Abstract:

During necropsy of a specimen of Lagothrix cana (É. Geoffroy, 1812) (Primates: Atelidae) from the Brazilian Amazon, pinworms were found in the large intestine. The intensity of infection was 64 parasites (17 males and 47 females) and there were no gross pathological changes related to parasitism. After morphological analysis the parasites were identified asTrypanoxyuris (Paraoxyuronema)lagothricis (Buckley, 1931) (Nematoda: Oxyuridae). This is the first record of this oxyurid species in primates in Brazil.

Abstract:

Ecological and morphological traits of fruiting trees, such as spatial distribution (Levey et al. 1984), crop size (Howe & vande Kerckhove 1981, Korine et al. 2000, Leighton 1993, Murray 1987), local availability of fruit (Sargent 1990), seed size or pulp/seed mass ratio (Julliot 1996a, Leighton 1993, McConkey et al. 2002, Russo 2003, Stevenson et al. 2005) and nutritional value and concentration of secondary compounds (Leighton 1993, Milton 1980, Sallabanks 1993), influence fruit preference in animals. In general, frugivores maximize energy intake by consuming ripe fruit with smaller seeds, higher pulp/seed ratio, bigger crop size, more nutritional fruits or fruits with fewer secondary compounds (Howe & vande Kerckhove 1981, Julliot 1996a, Korine et al. 2000, Leighton 1993, Milton 1980, Murray 1987, Russo 2003, Stevenson et al. 2005).

Abstract:

LINE-1 sequences have been linked to genome evolution, plasticity and speciation; however, despite their importance, their chromosomal distribution is poorly known in primates. In this perspective, we used fluorescence in situ hybridization (FISH) to map LINE-1 probes onto two representative platyrrhine species, Aotus nancymaae (Cebidae) and Alouatta belzebul (Atelidae), both characterized with highly rearranged karyotypes, in order to investigate their chromosomal distribution and role and to better characterize the two genomes. We found centromeric enrichment of LINE-1 sequences on all biarmed and acrocentric chromosomes co-localized with heterochromatin C-positive bands. This distribution led us to hypothesize that LINE 1 sequences may have a role in the centromere architecture and karyotype organization of platyrrhine genomes.

Abstract:

Infant care is known to impose high energetic costs on female primates because in addition to lactation, most primate mothers also provide transport for their offspring. Many studies have documented the high energetic costs of lactation, but less is known about energetic costs of infant carrying and their effects on the recovery of maternal physical condition. We compared the activities of female northern muriquis (Brachyteles hypoxanthus Kuhl, 1820) over a 12-month period at the RPPN Feliciano Miguel Abdala, Minas Gerais, Brazil to investigate whether mothers during their weaning year behaved differently than mothers in their post-weaning year, when they resumed reproductive cycling and copulating, and conceived again. We found no significant differences in the behavioral activity budgets of mothers in their weaning year (n = 4) versus post-weaning year (n = 5), despite the significantly higher proportion of time that mothers in their weaning year spent in close proximity with their infants and carrying their infants compared to mothers in their post-weaning year. We suggest that the energy budgets of weaning are similar to those of post-weaning in female northern muriquis.

O macaco-barrigudo (Lagothrix lagothricha) é um antropóide pertencente à Família Atelidae que possui os maiores primatas neotropicais. Um cadáver fêmea de macaco-barrigudo foi fixado com solução de formaldeído a 10%, posteriormente dissecado com o auxílio de lupa estereoscópica e fotodocumentado. O plexo braquial originou-se dos nervos espinhais C5 a C8 e T1, formando os troncos cranial, médio e caudal, dos quais derivaram os nervos periféricos que se assemelharam na origem e no território de inervação com os plexos de outros primatas, com exceção do nervo musculocutâneo que atravessou o músculo coracobraquial. Pesquisas sobre o plexo braquial de primatas fornecem dados que disponibilizam o acesso a informações valiosas sobre a morfologia destes animais e auxiliam no estabelecimento de parâmetros anatômicos entre as espécies, contribuindo também no tratamento de injúrias e procedimentos anestésicos.

There are a few studies about predation on primates. Howler monkeys, being relatively large animals, were believed to be preyed on successfully only by medium to large-sized carnivores and large birds of prey. Our study took place at Chácara Payquerê, which is situated in the municipality of Balsa Nova, State of Paraná, Southern Brazil. Fingers and nails from Alouatta guariba clamitans Cabrera, 1940 were founded in two faecal samples from Leopardus pardalis (Linnaeus, 1758). With our documentation large howler monkey remains in faeces, the possibility of ocelot being a potential predator of all Neotropical primates should be taken into consideration.

Abstract:

Neste estudo analisou-se a variação geográfica e não-geográfica de táxons de bugios, gênero Alouatta Lacépède, 1799, que ocorrem no Brasil, com o objetivo de esclarecer a taxonomia do grupo. Para a análise morfológica, examinou-se um total de 1.286 espécimes mantidos em cinco museus brasileiros e dois norte-americanos. O material consistiu basicamente de peles, crânios e ossos hióides; esqueletos e espécimes preservados em via úmida foram escassos. O estudo se baseou na análise qualitativa dos complexos morfológicos em adição a 18 morfométicos do crânio e osso hióide. Antes das decisões taxonômicas, elaborou-se um estudo de variação geográfica, sexual, ontogenética e individual. Reconheceu-se 10 espécies de Alouatta ocorrendo no Brasil, sendo a maioria definida por caracteres discretos, porém diagnósticos. São elas: Alouatta caraya (Humboldt, 1812), A. fusca (Geoffroy Saint-Hilaire, 1812), A. clamitans Cabrera, 1940, A. belzebul (Linnaeus, 1766), A. discolor (Spix, 1823), A. ululata Elliot, 1912; A. juara (Linnaeus, 1766), A. macconnelli (Humboldt, 1812), A. puruensis Lönnberg, 1941 e A. nigerrima Lönnberg, 1941. Alouatta macconnelli e A. clamitans mostraram notável variação geográfica na coloração da pelagem e algumas variáveis morfométricas (polimorfismo) o que dificultou as definições e limites dos táxons. Alouatta belzebul apresentou variação em mosaico na coloração da pelagem. Alouatta ululata e A. puruensis foram definidas pela presença de dicromatismo sexual na pelagem, mas este caráter pode ser um artefato e necessita estudos adicionais para corroborar sua validade. Sinonimizou-se Alouatta belzebul mexianae Hagmann, 1908 com A. discolor; e a validade de Alouatta seniculus amazonica Lönnberg 1941, não foi considerada.

Abstract:

The genus Alouatta (howler monkeys) is the most widely distributed of New World primates, and has been arranged in three species groups: the Central American Alouatta palliata group and the South American Alouatta seniculus and Alouatta caraya groups. While the latter is monotypic, the A. seniculus group encompasses at least three species (A. seniculus, A. belzebul and A. fusca). In the present study, approximately 600 base pairs of the g1-globin pseudogene were sequenced in the four Brazilian species (A. seniculus, A. belzebul, A. fusca and A. caraya). Maximum parsimony and maximum likelihood methods yielded phylogenetic trees with the same arrangement: {A. caraya [A. seniculus (A. fusca, A. belzebul)]}. The most parsimonious tree had bootstrap values greater than 82% for all groupings, and strength of grouping values of at least 2, supporting the sister clade of A. fusca and A. belzebul. The study also confirmed the presence of a 150-base pair Alu insertion element and a 1.8-kb deletion in the g1-globin pseudogene in A. fusca, features found previously in the remaining three species. The cladistic classification based on molecular data agrees with those of morphological studies, with the monospecific A. caraya group being clearly differentiated from the A. seniculus group.

Abstract:

Se ha reportado que algunos sistemas productivos simples y complejos pueden ser usados como hábitat temporal o permanente por parte de algunos primates. En el sur de México y Brasil se reportó que plantaciones forestales de Eucalyptus sp pueden mantener poblaciones de Alouatta spp. Sin embargo, hay aspectos sobre el uso de áreas productivas que no han sido descritos. Por lo tanto, es importante explorar cómo los primates utilizan estos espacios, para generar información útil en la formulación de planes de manejo y conservación de la especie. Aquí, reportamos la observación de un grupo de Alouatta seniculus en actividades de descanso y desplazamiento en plantaciones forestales de Eucalyptus urograndis en el departamento de Antioquia, Colombia, a partir de observaciones ocasionales.

Abstract:

The yellow-tailed woolly monkey,Lagothrixflavicauda(Humboldt, 1812), is a large atelid endemic to the cloud forests of Peru. The identity of this species was uncertain for at least 150 years, since its original description in 1812 without a voucher specimen. Additionally, the absence of expeditions to the remote Peruvian cloud forests made it impossible to collect material that would help to confirm the true identity ofL.flavicaudaduring the 19th and first half of the 20th century. Until now, the specimens ofL.flavicaudacollected by H. Watkins, in 1925, in La Lejía (Amazonas, Peru) were thought to be the oldest ones deposited in any scientific collection. Nevertheless, after reviewing the databases of the several international museums and literature, we found one specimen ofL.flavicaudadeposited at the Muséum National d’histoire Naturelle (Paris, France) collected in 1900 by G.A. Baër, in the most eastern part of San Martín (Peru), where the presence of this species was not confirmed until 2011. Thus, Baër’s specimen represents the oldest known specimen of the yellow-tailed woolly monkey and the only one coming from the eastern part of the species’ distribution. Finally, we highlight the importance of online scientific databases for easily diagnosable species. However, caution needs to be taken when using them. We also discuss the value of scientific collections as sources of new discoveries.

Abstract:

Lice are highly specialized parasites that spend their entire life cycle on their host. Thus, a particular species of chewing lice is often restricted either to a single host species or to a phylogenetically related species. About 560 species of these insects parasitize mammals exclusively. Cebidicola semiarmatus is one of these species, known to parasitize several primate species of the genus Aloautta. This paper presents the first record of C. semiarmatus parasitizing A. guariba clamintans.

Abstract:

Dung beetles are among the most important insects in the Neotropics. Some species use a wide range of food sources, whereas other species are highly specialized. This study compares the use of two-primate excrement by an assemblage of dung beetles in a tropical forest in Colombia. Dung ofLagothrix lagotrichaandAlouatta seniculuswas used to attract beetles. A total of 32 species (47.7% of the species recorded for the area) were found on the two types of excrement studied, demonstrating that primate excrement is an important resource. The niche overlap between both feces is 27.03%, which indicates a high degree of resource specialization. Although these two primate species are found in the same areas, their diets vary greatly to permit a high degree of differentiation in beetle species. A study that includes dung of others primates would create a more complete panorama of resource overlap in the assemblage.

Abstract:

Alouatta belzebul é uma espécie de bugio, da família Atelidae e gênero Alouatta, conhecido por guariba-de-mãos-vermelhas. É endêmico no Brasil, ocorrendo em duas populações: na Amazônia e na Mata Atlântica do litoral do Nordeste. A anatomia deste gênero apresenta variações entre os primatas, como o desenvolvimento atípico da laringe. Estas variações ocorrem principalmente por fatores comportamentais, defesa de alimentos e território. O objetivo deste estudo foi estabelecer dados comparativos das estruturas do sistema respiratório de A. belzebul com a de outros primatas humanos e não humanos e mamíferos. Foram usados para este estudo sete espécimes de A. belzebul onde observou-se na laringe a presença de musculatura, membranas e ligamentos, em consonância às estruturas observadas em primatas humanos, e um osso hioide bastante evidente. A traqueia do Alouatta belzebul é constituída de 11 a 12 anéis cartilagíneos incompletos. Nas estruturas pulmonares, notou-se um quarto lobo no pulmão direito, no esquerdo apresenta somente dois lobos, que se assemelharam com outros primatas não humanos, como sagui-de-tufos-brancos (Callithrix jacchus) e macaco-prego (Sapajus libidinosus), mamíferos domésticos, como canídeos e felinos e mamíferos silvestres, como jaguatirica (Leopardus Pardalis) e raposa (Cerdocyon thous). O estudo contribuiu para discussão sobre aspectos evolutivos do sistema respiratório e atuação clínica e cirúrgica do médico veterinário.

Abstract:

Se ha considerado que la matriz del paisaje actúa como una barrera que influye en la dispersión, diversidad y persistencia de algunas especies de fauna, pero su importancia no ha sido evaluada en detalle para primates arborícolas. Investigaciones del género Alouatta han reportado desplazamientos terrestres entre parches de bosque sugiriendo cierta plasticidad comportamental que ayuda al uso eficiente de recursos en fragmentos reducidos. Adicionalmente al uso de la matriz para desplazamiento, se ha estimado para Alouatta pigra, un alto porcentaje de tiempo destinado al descanso en este tipo de cobertura. Aquí reportamos dos registros ocasionales del uso de sabanas para el descanso y forrajeo por parte de individuos de Alouatta seniculus en una zona de transición entre el piedemonte y sabanas drenadas de la altillanura, en el departamento del Meta, Colombia.

Abstract:

The development of the interactions of an infant primate with its mother and the other members of its social group plays a special role in the ethology and demography of the species, with consequences for their survive and their conservation. The objective of the present study is to investigate the development of an infant of Alouatta guariba (Humboldt, 1812) in the wild, its behavior and interactions during its first seven months of age, in a remnant of Araucaria Pine Forest in Paraná State, Brazil. Using the method of instantaneous scanning with 5 min intervals, a total of 46 hours and 15 minutes of direct observation (555 individual records) showed that the infant behavioral patterns during its first four months were characterized by high dependency, which decreased progressively until the appearance of typically juvenile behaviors during the remaining 3 months. The first records of feeding on solid food, tail functionality and allomaternal care were also recorded and discussed. This work contributes to an understanding of the ontogenetic development of a poorly known aspect of this species, and thus for a more understanding of the genus Alouatta Lacépède, 1799.
